“…The global population is expected to increase to 9 billion by 2050. Therefore, rice breeders need to develop new and improved cultivars of rice that have higher yields and adaptation to different biogeographic regions [ 63 , 64 , 65 , 66 ]. CWRs of rice can provide genetic resources for these important traits as they are adapted to wide geographic ranges and are tolerant to many biotic and abiotic stresses [ 63 , 67 , 68 ].…”

The flavin monooxygenase (FMO) enzyme was discovered in mammalian liver cells that convert a carcinogenic compound, N-N′-dimethylaniline, into a non-carcinogenic compound, N-oxide. Since then, many FMOs have been reported in animal systems for their primary role in the detoxification of xenobiotic compounds. In plants, this family has diverged to perform varied functions like pathogen defense, auxin biosynthesis, and S-oxygenation of compounds. Only a few members of this family, primarily those involved in auxin biosynthesis, have been functionally characterized in plant species. Thus, the present study aims to identify all the members of the FMO family in 10 different wild and cultivated Oryza species. Genome-wide analysis of the FMO family in different Oryza species reveals that each species has multiple FMO members in its genome and that this family is conserved throughout evolution. Taking clues from its role in pathogen defense and its possible function in ROS scavenging, we have also assessed the involvement of this family in abiotic stresses. A detailed in silico expression analysis of the FMO family in Oryza sativa subsp. japonica revealed that only a subset of genes responds to different abiotic stresses. This is supported by the experimental validation of a few selected genes using qRT-PCR in stress-sensitive Oryza sativa subsp. indica and stress-sensitive wild rice Oryza nivara. The identification and comprehensive in silico analysis of FMO genes from different Oryza species carried out in this study will serve as the foundation for further structural and functional studies of FMO genes in rice as well as other crop types.

“…The aim of these efforts is to increase farmer income, secure food supply, and preserve the natural environment. Therefore, the adoption of new practices in rice cultivation contributes to the Sustainable Development Goals (SDGs) of the United Nations, and in particular goal 1 no poverty, and 2 zero hunger (Ehiakpor et al, 2021; Samal et al, 2022). In addition, this crop contributes to sustainable production systems (Samal et al, 2022), in line with SDG 12, and even water efficiency, SDG 6, when management practices decouple production from the degradation of the natural environment (Ali et al, 2018).…”

Rice is a crop that contributes significantly both to food security and to ensure adequate income levels for farmers. This motivates efforts in many countries to disseminate techniques that increase production while being environmentally friendly and affordable to small farmers. The objective of this article is to study the process of adoption of innovations in rice cultivation in Ecuador. Four practices that increase yields and improve natural resource management have been selected: land leveling, certified seed, widely spaced transplanting, and the use of harvesting machinery. The factors that most influence their adoption are studied for each of them: human and social capital, and institutional support for agriculture. In addition, the interrelations of some practices with others are analyzed. Multivariate probit estimation shows that education is the main factor that increases the probability of adopting these practices. And with unequal incidence are associationism, access to credit and insurance. The complementarities found between different practices point to the convenience of promoting them jointly to take advantage of their synergies.

“…Rice is a key food crop that is produced in many countries around the world and feeds a large part of the world’s population ( IRRI, 2006 ; Kaur and Pati, 2017 ). This crop is important for global food security since it is consumed by most of the world’s poor people ( Samal and Babu, 2018 ; Kandil et al., 2022 ). Rice demand is expected to increase with population growth by 2050 and reach values of 607 million tons based on current consumption ( Samal and Babu, 2018 ; Gérardeaux et al., 2021 ).…”

The effect of different foliar sprays numbers of cytokinins – (CK) and brassinosteroids – (BR) on the physiological, biochemical, and panicle parameters of rice plants subjected to combined heat stress (high day/night temperatures) were studied in three different experiments. The treatments established for the first (E1) and second (E2) experiments were the following: i) absolute control, ii) stress control, iii) heat stress + one foliar spray of CK, iv) heat stress + two foliar sprays of CK, v) heat stress + three foliar sprays of CK, vi) heat stress + one foliar spray of BR, vii) heat stress + two foliar sprays of BR, or viii) heat stress + three foliar sprays of BR. For the third experiment (E3), the treatments were the following: i) absolute control, ii) stress control, iii) heat stress + three foliar applications of CK, iv) heat stress + three foliar applications of BR. Rice-stressed plants and sprayed with three foliar sprays of CK or BR had a better stomatal conductance in E1 and E2 compared to their heat-stressed control. The relative tolerance index suggests that three CK or BR applications helped to mitigate the combined heat stress in both experiments. The foliar CK or BR applications at the flowering and grain-filling stages in rice-stressed plants increased Fv/Fm ratio and panicle characteristics (number of filled spikelets and the percentage of panicle blanking in E3). In conclusion, foliar applications of BR or CK can be considered an agronomic strategy to help improve the negative effect of combined heat stress conditions on the physiological behavior of rice plants during different phenological stages.
